ADJUSTABLE SHADE.

Specification of Letters Patent.

Patented Aug. o, 1918.

Application filed. March 1,1918 Serial No. 219,894.

To all whom it may concern:

Be it known that I, RICHARD I. MILLS, a citizen of the United States ofAmerica, residing at Roosevelt, in the county of Duohesne and State ofUtah, have invented certain new and useful Improvements in AdjustableShades, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to an adjustable shade for lamps and the like andhas for its object the production of a simple and ellicient meanswhereby the sides of the shade may be swung outwardly to a position forincreasing the radiancy of the lamp upon which the shade is used.

Another object of this invention is the production of simple andefficient means for holding the hinged portion of the shade againstaccidentally swinging to a closed position.

With these and other objects in view this invention consists of certainnovel constructions, combinations and arrangements of parts as will behereinafter fully described and claimed.

In the drawings:

Figure 1 is a side elevation of the lamp shade, certain portions thereofbeing shown in dotted lines as swung outwardly.

Fig. 2 is an enlarged vertical section through one side of the lampshade.

Fig. 3 is a top plan view of the top plate, or blank from which the topplate is formed.

Fig. 4 is a plan view of the blank from which one of the side sectionsor plates of the upper portion of the lamp is formed.

Fig. 5 is a plan view of the blank from which one of the lower hingedsections of the lamp shade is formed.

Fig. 6 is a section taken on line 6-6 of Fig. 1.

Fig. 7 is a section taken on line 7-7 of Fig. 1.

Fig. 8 is a section taken on line 88 of Fig. 1.

Fig. 9 is a horizontal section taken on line 9 9 of Fig. 2.

By referring to the drawings it will be seen that 1 designates the topplate which is provided with centrally located parallel shades 2 havinga plurality of radiating shades 3 extending therefrom which shades areadapted to bend upwardly for fitting snugly upon the lamp socket 4.

The lamp shade is formed rectangular or square and comprises a primarypair of side plates 5 and a pair of auxiliary side plates 6. Each of theplates 5 and 6- are provided with overhanging flanges 7 fittin snuglyover the top plate 1 and being soldered or otherwise fixed thereon. Theside plates 6 are provided with side flanges 8 which side flanges 8overhang the side plate 5 as shown clearly in Fig. 1 of the drawings.The lower edge of each side plate 5 and 6 is provided with a pluralityof elongated slots 9 for producing a plurality of tongues 10. Thealternate tongue 10 is folded backwardly upon itself and constitutes ahinge 11 for fitting over the pintlepin 12.

A pair of primary hinged plates 13 are secured to the plates 5 and apair of auxiliary plates 14 are secured to the plates 6. These plates 14are provided with under hanging flanges 15 which under hanging flanges15 extend under or ungder-lap the edges of the plate 13. Each plate 13and 14 is provided with a plurality of slots 16 formed near the upperedge thereof for dividing the upperedge of the plates 13 and- 14 into aplurality of tongues 17. Each alternate tongue 17 is bent backwardlyupon the top of this respective plate for forming a hinge and fittingsnugly over and upon the pintle pin 12. In this manner the upper plates5 and 6 will be fixedly hinged to the plates 13 and 14 or either to thealternate tongues 17 and the plates 13 and 14 and the alternate tongues10 of the plates 5 and 6 extend parallel with the top of theirrespective plates, and tongues of the upper plates fitting between thetongues of the lower plates, the edges of the tongues frictionallyengaging each other thereby causing the side plates 13 and 14 to beswung and easily held in an adjustable position with respect to theplates 5 and 6. It will be seen that any one of the plates 13 or 14 maybe swung outwardly, to suit the convenience of the operator.

What is claimed is A lamp shade, comprising a top plate, on
